  1. Introduction to Microphones

  2. What is a Microphone? Microphones are a type of transducer: a device which converts energy from one form to another

  3. Two general types of mics Dynamic mics Condenser mics

  4. Two general types of mics Dynamic mics • No power required • Magnetic diaphragm acts like a sail – generates electricity via a magnet • Only react to strong sounds • Rugged, short range, low sensitivity Condenser mics

  5. Two general types of mics Dynamic mics • No power required • Magnetic diaphragm acts like a sail – generates electricity via a magnet • Only react to strong sounds • Rugged, short range, low sensitivity Condenser mics • Don’t create electricity – use charge from battery source • More sensitive, greater range, much more fragile

  6. Mic Types Handheld Shotgun Lavaliere (Lav) PZM (Pressure Zone Mic)

  7. PICKUP PATTERNS/DIRECTIONALITY Omnidirectional • Picks up 360-degrees

  8. PICKUP PATTERNS/DIRECTIONALITY Cardioid • Picks up in heart-shaped pattern

  9. PICKUP PATTERNS/DIRECTIONALITY Unidirectional (or Hypercardioid) • Picks up in forward/shotgun-type pattern

  10. PICKUP PATTERNS/DIRECTIONALITY Bi-directional • Picks up in figure-8 pattern/equally both sides

  11. MIC CONNECTIONS XLR • Three-pin

  12. MIC CONNECTIONS 1/4” • Also called “Headphone”

  13. MIC CONNECTIONS 1/8” • Also called “Mini”
